项目摘要

The objective of this project is the synthesis of novel heptazine (C6N7) based materials and their use as metal free photocatalysts. Polymeric carbon nitrides, which have recently gained remarkable attention as metal free semiconductors for photocatalytic water splitting, are composed out of condensed heptazine units. However, such polymeric carbon nitrides can just be prepared at high temperatures, which make a control of their nanostructure and morphology as well as an alteration of their chemical structure extremely difficult. In this project we therefore aim for the synthesis of defined molecular heptazine derivatives, which can then be transferred into heptazine-based materials in a controlled manner. On the one hand heptazine derivatives will be synthesized, which can build up supramolecular structures by non-covalent bonds. Controlled carbonisation of these heptazine aggregates should then yield nanostructured polymeric carbon nitrides. On the other hand it is planned to prepare heptazine derivatives which can act as monomers for the synthesis of microporous polymer networks (MPNs) or covalent organic frameworks (COFs) with high permanent surface areas. The here proposed concept will therefore yield in novel metal-free photocatalysts, with the possibility to tailor their chemical and electronic structure, as well as their surface area and morphology.
本项目的目标是合成新型的基于七嗪(C6N7)的材料及其作为无金属光催化剂的用途。聚合碳氮化物是由稠合的七嗪单元组成的,最近作为光催化分解水的无金属半导体而受到了极大的关注。然而,这种聚合碳氮化物只能在高温下制备,这使得控制它们的纳米结构和形态以及改变它们的化学结构极其困难。因此,在这个项目中,我们的目标是合成定义的分子庚嗪衍生物,然后可以以受控的方式将其转移到庚嗪基材料中。一方面合成了七嗪衍生物,通过非共价键形成超分子结构。然后,这些七嗪聚集体的受控碳化应产生纳米结构的聚合碳氮化物。另一方面,计划制备七嗪衍生物,其可以充当用于合成具有高永久表面积的微孔聚合物网络(MPN)或共价有机框架(COF)的单体。因此,本文提出的概念将产生新型无金属光催化剂,并有可能调整其化学和电子结构以及其表面积和形态。
